Maytansinoid B is an ADC Cytotoxin that can be coupled with antibodies to form Antibody-Drug Conjugates (ADCs). Maytansinoids are known antimitotic agents that bind to tubulin and inhibit microtubule assembly. Maytansinoids can induce cell cycle arrest at G2/M, thereby inducing apoptosis.

Biological Activity


ln Vitro Maytansinoid has cytotoxic action against a range of tumor cell lines, including lymphoma lines, with concentrations between 10 and 90 pM [1]. SAR3419, which combats B-cell malignancies, is created when maytansinoid and anti-CD9 antibodies interact [1].

Solubility Data


Solubility (In Vitro) DMSO : 100 mg/mL (136.01 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (3.40 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (3.40 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)

1 mM 1.3601 mL 6.8003 mL 13.6006 mL

10 mM 0.1360 mL 0.6800 mL 1.3601 mL
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
